Miller, currently serving a six-game suspension for violating the NFL's substance abuse policy, was cited for speeding and driving with a suspended license last week near his home in Arapahoe County after being pulled over for driving 13 miles per hour above the speed limit.

"Everyone here has an individual responsibility to not only themselves but to this organization as well as to this football team," Fox said. "It's something we're not pleased about, and we'll leave it at that."

Miller was not arrested after the traffic stop last week, and his father, Von Sr., was allowed to take over driving the vehicle.

The officer who issued Miller the citation made sure to write on the ticket that Miller would have to appear in court, perhaps a reference to Miller's August arrest for failing to appear in court on a 2012 traffic citation.

Miller has declined all interview requests since issuing a statement through the NFL Players Association on Aug. 20 when his suspension was announced by the NFL. He is allowed to work out individually at the Broncos' facility and attend meetings with his teammates while serving his suspension.
